A rotary feedthrough for a compressed air supply system is provided between a stator and a rotor rotating relative to this stator. A compressed air channel disposed in the stator is connected to a compressed air line and leads into an annular chamber formed in the rotor, from which at least one working channel leading to a consumer proceeds. The stator is connected in the region of the rotary feedthrough to a control line. A moment of friction occurring in the region of the rotary feedthrough resulting in premature wear is reduced by providing a switchable non-return valve in the annular chamber. Blocking elements which extend within the annular chamber concentrically to the rotational axis of the rotor are moveable into an open position by an actuating element, which is displaced from the stator in the direction of the blocking elements.

A drive system for a self-propelled harvesting machine includes a drive engine, designed as an internal combustion engine, a transfer gearbox driven by the drive engine that includes a first driven pulley which is disposed on a drive shaft for driving at least one drive pulley of a working mechanism using a first belt, and at least one hydraulic pump for driving a further working mechanism. A second output pulley is assigned to the transfer gearbox and drives the at least one hydraulic pump using a second belt.

Drive system for a self-propelled harvesting machine

A drive system for a self-propelled harvesting machine includes a drive engine designed as an internal combustion engine, a first driven pulley driven by the drive engine that at least one drive pulley of a working mechanism via a drive belt. The drive system also includes at least one first and one second hydraulic unit. The drive belt is drivably connected to a pulley that is enclosed in sections by housing elements. The housing elements are disposed opposite one another and are fixed relative to the pulley. The first hydraulic unit and the second hydraulic unit are disposed on the housing elements and, the first hydraulic unit and the second hydraulic unit are drivably connected to a shaft that extends through the pulley.

A method for adjusting the pressure in at least one first and one second tire of a vehicle from a starting value to a target value, includes that the target value is located between the starting value and a pressure of a pressure reservoir. The method includes allowing air to flow through a first line between the first tire and the reservoir and through a second line between the second tire and the reservoir, determining which tire is likely to reach the target value sooner and throttling the air flow through the line of the tire identified in the determining increasing the air flow through the line of the tire that was not identified in the step of determining.
